MODE FOR CARRYING OUT THE INVENTION

Description will be presented with reference to FIGS. 7 to 9.

FIG. 7 illustrates a first component object 20. A second component object 20′ is to be inserted in the component object 20, and when a process of surrounding the second component object 20′ with a predetermined material is needed after the second component object 20′ is inserted, a protective region (see FIG. 8) surrounding the second component object 20′ may be generated according to the position of the second component object 20′.

According to preset conditions, one material may be assigned on the protective region and printed according to the assigned material.

Referring to FIG. 9, when the second component object 20′ is doubly surrounded, a first region surrounding the second component object 20′ and a second region surrounding the first region are provided, and the first and second regions may be assigned with materials different from each other. For example, the first region may be assigned with a rigid material, and the second region may be assigned with a flexible material.

Subsequently, referring to FIG. 10, when a lighting is realized by incorporating a lamp such as LED through an electrical circuit configuration, in order to apply the light amount uniformity according to the design of the first component object and the optimized amount of radiated light when lamps are disposed in the first component object 20, functions of automatically checking the light amount and arranging the lamps may be provided.

For example, considering a lighting function, when a well-known simulation program is used to incorporate the lamps into the first component object 20, it is necessary to calculate the number of output lamps required, where the lamps should be located for excellent radiation, what components are needed, and where the optimal position is. Considering light radiated at this time, an optimal position disposition and required kinds of components may be selected and disposed.

The well-known light amount simulation program and a main controller 100 cooperate with each other such that the first component object 20 is selected; a light amount radiated from the lamps for each region of the first component object 20 from the light amount simulation program is inputted; and at least any one of the thickness, material of the first component object 20 and the type, number, or position of lighting modules disposed inside is allowed to be set so that a specific amount of light is radiated for each region of the first component object 20. According to the type, number and position of the lighting modules specified as such, a power supply module for supplying power is disposed.

According to the above-described configuration, an embodiment of 3D printer outputting method for mounting electrical component according to the present invention will be described as follows.

Data about electrical component, data about electrical circuit disposition, and the like are inputted to a general 3D modeling data 110.

A main controller 100 of a 3D printer calculates and controls the corresponding configuration to be automatically positioned according to previously input data to thereby configure a product.

For example, a lattice internal structure 10 is formed to prevent the collisions between the positions of LED, battery, and micro-computer. Coordinate values are determined by a coordinate generating unit (a coordinate system 140) with the center point of a unit structure 15 of the structure 10 as a reference point.

When a component object 20 is mounted on the structure 10, the colliding or overlapping portion of the component object is identified by using the coordinate generating unit 140, and whether the component object 20 is supported by the unit structure 15 is determined, and the colliding or overlapping portions or unsupported portions are rearranged at other dimensions using merits of three-dimension.

In addition, in order to automatically insert the actual component object 20, the component object is picked up by a well-known pickup device 30, and the point in time and the position at which a second component object 20′ is inserted in the first component object 20 are predetermined.

For a 3D printer without a pickup function, the time point at which the component object 20′ can be directly inserted manually is provided to notify the time point, and a cover is automatically generated for replaceable component objects such as battery or LED, thereby preventing the designed external shape from being damaged.

In order to protect the component object, a material different from that of the external shape of the component object is applied to the inside and outside of the component object.

In the above configuration, when a lamp such as LED is incorporated to realize a lighting lamp, uniformity of light amount according to the design of the first component object 20 and the application of optimized light amount radiated when the lamp is disposed in the first component object 20 are designed.

FIG. 11 illustrates a 3D printer output system for mounting electrical components.

When 3D modeling data 110 is read and is converted into a format for 3D printers (tool path format such as G-code), if a prepared specified configuration is selected in 3D modeling to realize a electrical configuration or functions corresponding thereto, the configuration is automatically positioned and configures a product according to the input data inputted by a main controller of a 3D printer, and 3D printing is performed through an output unit part 130.

For example, when an LED element is configured from among electrical configurations and an on/off function is needed in a specific condition, an LED, a battery, and a micro-computer and a circuit which controls the LED and the battery are required. To this end, the positions of the LED, battery, and the micro-computer should be set, and a circuit for connecting these should be configured.

At this time, the positions and circuit are automatically configured by the calculation of the main controller 100 which are inputted and preset from the 3D modeling data 110, and thus, a user may easily realize the electrical configuration. Here, an interface (UX-based GUI environment, etc.) is provided such that the positions of the LED and the inserting position of the battery may be changed by the user.

FIG. 1 illustrates a lattice internal structure 10 is formed to dispose the LED, the battery, and the micro-computer (hereinafter, referred to as “component objects”) without collision between the positions the component objects.

In this document, the word “component objects” do not simply mean only the circuit but may mean objects including all of circuits required for electrical operations and/or electrical lines (wires) and/or power source (battery), etc.

The structure 10 is formed of a plurality of unit structures 15 having a predetermined shape.

The unit structure 15 of FIG. 1 has a hexagonal outer periphery and a circular inner diameter. Coordinate values are determined by a coordinate generating unit 140 with the center point of the unit structure 15 as a reference point. Thus, according to the unit structure of the structure, various types of coordinates may be generated.

As in the above cases, a resultant object may be printed while new unit structures are generated through 3D printing, and on the other hand, may be formed such that the LED, the battery, and component objects and a circuit line connecting these are disposed on the resultant object in which shapes have been already printed through 3D printing.

Hereinafter, referring to FIGS. 2 and 3, a method will be described in which collision portions of component objects are identified by using a coordinate generation unit (coordinate system 140) and the collision portions are re-arranged in other dimensions by using merits of 3D.

In forming a structure 10, the structure 10 formed in a lattice shape is most desirable, and since having the lattice shape, the structure 10 has vacant spaces inside unit structures 15. A component object 20 is positioned on a structure 10. However, as illustrated in FIG. 2, since there is a case in which the component object 20 can not be supported by a unit structure 15 because the component object 20 is smaller than the unit structure 15, a main controller 100 should determine whether the component object 20 is supported by the unit structure 15. In the determination method, a coordinate value is calculated. As a result of determination, when the component object 20 is not supported by the unit structure 15, the component object 20 is moved or the structure 10 is to be modified so as to be supported by the structure 10. In FIG. 4, unit structures 15 of a structure 10 are modified to be formed in various shapes, and one of the unit structures 15 is configured to support a component object 20.

Next, referring to FIGS. 5 and 6, a method will be described in which when portions at which component objects 20 overlap in a structure 10 are inspected by using a coordinate generation unit 140, and when there is an overlapping portion, the portion is adjusted so as not to overlap.

Referring to FIG. 5, two component objects 20 and 20′ partially overlap each other. Accordingly, the positions of the component objects 20 and 20′ are adjusted with each other, the overlapping portion is removed as illustrated in FIG. 6.

The positions of the component object 20 is adjusted by using the coordinate generation unit 140 and then the component object 20 is positioned at a stable position.

When an actual 3D printer 1 outputs on the simulation formed as such, a pickup function of automatically inserting an actual component object 20 will be described with reference to FIG. 7.

In 3D modeling, when there is a case in which a first component object 20 and a second component object 20′ are coupled, that is, when there is a case in which during the 3D printing of the first component object 20, the second component object 20′ should be coupled from the outside, the second component object 20′ should be picked up by a well-known pickup apparatus 30, and the time point and position for inserting the second component object 20′ into the first component object 20 should be previously determined.

Next, during the 3D printing of the first component object 20, the second component object 20′ is to be inserted by the pickup apparatus 30 at the pre-calculated time point and position. When the second component object 20′ is inserted by the pickup apparatus 30 at the pre-calculated time point and position, it is important to make the second component object 20′ not to deviate from a region.

In addition, since the time point and position of insertion vary according the shape of the second component object 20′, this should also be considered in calculation. Furthermore, after the second component object 20′ is inserted, the time point and position of remaining printing with respect to the first component object 20 should be considered.

In order to reliably attach the above component object (or a circuit such as micro-computer) to an existing printed resultant object when the component object is inserted, an adhesive with a certain shape may be applied on the surface of the component object or the surface of the resultant object, and when a plurality of circuits are inserted, whether each circuit is electrically well connected may also be tested.

The 3D printing data in which the time point and position of pickup are calculated is outputted by an actual 3D printer 1.

For a 3D printer without a pickup function, the time point at which the component object 20′ can be directly inserted manually is provided to notify the time point, and a cover is automatically generated for replaceable component objects such as battery or LED, thereby preventing the designed external shape from being damaged. At this time, the automatically generated cover is to be outputted in a detachable shape together or separately in other region when 3D printing is outputted.

For example, when a 3D resultant object having an LED lighting is formed by 3D printing, the LED lighting, a power source, switches and electrical lines (wires) for connecting the power source and the lighting should be inserted into the 3D resultant object.

Accordingly, when printing with a 3D printer cooperating with a pickup apparatus, if a position which is pre-calculated by a coordinate generation unit, and at which component objects or the like (including electrical lines (wires) and/or a power source) should be inserted is reached during printing, the pickup apparatus is operated to pickup the objects (an LED lighting, wires, a power source or the like) to be inserted in respective positions and position the objects at the corresponding positions, and a resultant object is thereby completed. (In this case, adhesives or the like may be used.)

Meanwhile, in case of a 3D printer which do not cooperate with a pickup apparatus, if a position which is pre-calculated by a coordinate generation unit, and at which component objects or the like should be inserted is reached during printing, unlike the above case, the size, volume, and position of respective components (which are calculated by the main controller or coordinate generation unit through receiving 3D printing data) are calculated, and the remaining portions except for spaces in which the components are inserted, are formed by 3D printing, and required components are inserted later in the space by a user and may be used.

At this time, since in the case as described above, the printed resultant object has a space which remains vacant and in which component objects or the like are inserted, the printed resultant object does not have an originally intended 3D shape and is weak against dust or other shocks. Accordingly, a cover for blocking dusts or the like while maintaining the original designed shape may be produced through the above-described method.

Meanwhile, for the protection of the objects and safety, various output materials are formed inside or outside to match usages and thereby improving the efficiency.

There are provided functions for protecting the component objects. By the functions, different flexible materials are formed between outer shapes of component objects and target output objects to protect the internal objects; and regions such as outer shapes of a sharp portion requiring safety or regions requiring damage prevention, waterproofness, electromagnetic wave blockage, or the like are automatically replaced with an output material according with the requirements.

For example, when a toy product having an electrical function is to be formed, the product should have an inner circuit, the outer appearance should not be sharp, and the product should not have problems of being inputted into a mouth or being wet, and should not be damaged when being thrown. To this end, the inside of the product brought into contact with component objects is formed with silicone, the outsides of the component objects are formed with a rigid plastic material which retains an external shape, and sharp portions are formed with flexible silicone to have an external shape and safety. In addition, when an elephant is designed, only nose portion can be replaced with silicone and thus the functionality of design is improved.

In a conventional 3D printer in which the above functions can not be realized, the position at which an electrical circuit (micro-computer or the like) is to be disposed is calculated in advance through the connection to a coordinate generating unit (coordinate system 140), and 3D printing may be performed considering this.
